A CORPORATION 'OI NEW YORK CONSTRUCTION OF CYLINDRICAL PACKAGES Application filed December 6,1929. Serial No. 412,113.

above, usually employ a core upon which the web material is rolled and subsequently wrapped. Such packages, because of their length, are usually transported, handled and stored on end, and accordingly are subjected to repeated and severe end-shocks which not infrequently seriously damage the edges of the packaged material at the opposite ends of v the roll. To prevent such damage it has been proposed to extend the core beyond the edges of the web material wound thereon, with the v, idea in view that the extended core would receive and absorb the end-shocks. This has,

however, not been successful because of end 3 p throughout the specification and claim in dewise shifting of the packaged material under normal conditions of handling, thereby.

bringing the edge of the web adjacent one or the other of the ends of the extended core where it is subjected to damage as before. It

has also been proposed to pad the end of the rolled web with excelsior, burlap or the like, but such construction is very expensive.

My invention provides a novel type of package for shipping web material such as felt base or linoleoum rugs, embodying a construction which eliminates the deficiencies of the types heretofore known. More particularly such construction comprises in combination, members projecting a substantial dis- 5 tance beyond each end of the rolled web and independent thereof which are adapted to re-f ceive and absorb all end-shocks, and means for positively preventing any substantial endwise shifting of the rolled web. These and other advantages will be fully apparent from thefollowing descriptions and the accompanying drawing.

In the drawing plete package constructed in accordance with my invention;

detail, the novel type of end construction of the package;

Figure 111 is'a sectional viewillustrating,

V in detail, a slightly modified type of end construction.

Referring now to the drawing, numeral 1 indicates a core for the package, usually in the nature of a tube. Preferably, the core ly greater in length than the width of the web .to be rolled thereon. Interfitting each open end ofthe tube 1, and united therewith is a shock-absorbing member 2 having a shoulder 4; This member is conveniently formed of wood and may be united with the tube by means of one or more nails 3. As clearly shown in the drawing the shock-absorbing members 2 project a substantial distance beyond the ends of the tube 1.. Wherever the expression substantial distance is used difference between the diameter of the rolled web and the diameter of the member 2. Defining the expression in another manner, the amount of projection is such that a'plane tan' gent to the periphery of the shock-absorbing member and the periphery of the end of the rolled web will form an angle of approxi mately with the longitudinal axis of the Pack ge- 5 r I At each end of thetube is an annular flat ring 5, havingan outside diameter-approximately equal to the diameter of the rolled web to be packaged, and a central opening of'such size as to fit over that portion of the shock-ab sorbing member 2 of smaller diameter and abut the shoulder 4 thereof. Preferably the central opening of thering 5 isof such a diand positively clamped between the end of r. the tube '1 and the Figure I 1s a perspective v1ew of the com V 7 shoulder 4 of the shockabsorbing member, The annular ring 5 is formed of any suitable material such as chip- .board or fibre board, having suffic ient strength and rigidity to prevent shearing;

thereof by the shouldered member through endwise movement of the packaged material.

The web to be packaged, as for example a felt base rug a, is closely wound about the core or tube 1, intermediate the annular rings 5 at each end. The rolled web is then securely Wrapped with heavy paper 6, the edge 7 of the paper being adhesively sealed.

To complete the package a cap 8, of gummed paper or fabric is applied over the ends. In Figure II is shown a preferred form in which the end oap isprovided with a central opening of the proper size to permit the cap to pass over and fit snugly about the: projecting member 2. According to this construction the capengages the outer surface of the annular ring 5, and extends overthe end of the out-side wrapper 6, adhesively engaging both ring and Wrapper and forming a strong union therebetween. This construction presents an extremely neat appearance to the package, no paper or fabric extending over the shock-absorbing members to-be torn, soiledor damaged in handling, etc. In Figure III is illustrated a modified construction in which the end cap 8- covers the projecting shock-absorbing member as well as the annular ring 5, and extends over and adhesively engages the outside wrapper 6.

It will be apparent that thenovel package construction eliminates the defects of the packages heretofore known and provides a strong construction capable of withstanding any shock arising in the usual course of shipping and storing the package without damage to its contents. The annular rings being securely retained against outward movement by the shouldered shock-absorbing members, positively prevent the contents of the package from any substantial e'ndwise movement. In addition, the rings pro-vide'a facing over the edges of'the rolled web thereby giving additional protection against damage. The shock-absorbing members, which are rigidly united with the core and positioned to extend a substantial distance beyond the end of the rolled web and the annular rings, serve to receive and absorb all end-shocks, thereby protecting the contents of the package from damage normally caused by such shocks.

WhileI have described a preferred embodi- I 'ment of my invention, certain modifications may be made without departing from the spirit thereof and I do not wish the scope of the invention to be limited except as defined in the appended claim.

I claim: An improved package for web material 1 comprising, in combination, a ,core upon Whl0h the web material may be'woun'd; shouldered, shock-absorbing members interfitting and united with the respective ends of said core; annular rings at each end of said core,

a plane tangent to the periphery of theshockabsorbing member and the periphery of the end of the packagedweb will form an angle of approximately with the longitudinal axis of the package;

In testimony whereof, I affix my signature.

WALTER VEIT.
